Can someone explain to me what all the names mean? I thought I had a handle on a few of them (esp on AB) and then I see a listing that confuses me. What, in strict definition, is, say, a mustard? A dragon? Etc? What are the definitions for these colors and patterns? Thanks!

Oh and also, do halfmoons ever come in CT? Both are my favorite, Id love to see them in the same fish!

I don't think HM's come as CT's because their a specific tail type. I have seen Plakat HM's and CT's but never HM/CT but that would be a very interesting breeding pair no? Dragon means double scales usually a lighter or darker color with fins that look literally like Dragon wings. Mustard means a dull yellow like actual mustard. Marble is color changing and Butterfly is a tail pattern commonly seen on HM's. (Kalona had the most beautiful and unique butterfly and colors. He was such a navy blue his blue only showed up in pictures. He was so blue he was black.)

But I see "mustard" with a blue body and yellow fins, and another "mustard" with a black body and yellow fins with black tips. Whats the definition of what makes a mustard, a mustard? Where is the color confined to? What are the hues acceptable? Etc

Only dragons Iv ever seen were white body with red fins, "red dragon". Do they come in other colors? What is the strict definition of colors and markings that make a "dragon". If theres fin-color on the head, is that no longer a dragon?

A CT is basically an HM with fin ray reduction. Some are delta's and super deltas too.

The dragons are known to have not only a normal set of scales but they have white or dark, dark coloring contrast to their normal's. The normal dragon you commonly see is a red Dragon with white scales but the notice is that some dragons have their scales up to their eyes forming almose a mask. Here's a pic of a dark green lace Dragon found on Aquabid.com

The colors primarily are a very dark blueish green on this male. (Note: I do not own him he was on sale on Aquabid and I wanted to save the pic just in case.)

EDIT: I had no idea Crowntail's were HM's with fin ray reduction. That's pretty cool.
